Deploying Django application - paradoxSid/notes GitHub Wiki

• Python brew install python3
• pip
• virtualenv pip3 install virtualenv
• awsebcli pip3 install awsebcli

• Go to the application base dir and activate virtualenv
• Create a folder with mkdir .ebextensions
• Create a file ./.ebextensions/django.config and add the below lines to

container_commands:
  01_collectstatic:
    command: "source /var/app/venv/*/bin/activate && python3 manage.py collectstatic --noinput"
    leader_only: true

option_settings:
  aws:elasticbeanstalk:container:python:
      WSGIPath: <PROJECT_NAME>.wsgi:application
  aws:elasticbeanstalk:environment:proxy:staticfiles:
      /static: static
  aws:elasticbeanstalk:application:environment:
      DJANGO_SETTINGS_MODULE: <PROJECT_NAME>.settings
      PYTHONPATH: "/var/app/current:$PYTHONPATH"

• Initialize eb cli with eb init -p python-3.6 <PROJECT_NAME>
  • Your aws-access-id or aws-secret-key can be found here.
• Create an environment and deploy your application to it with eb create.

eb create <ANY_NAME>

*** This may take upto 5 minutes ***

• Domain name of the new environment can be found with eb status under CNAME. Copy it.
• Inside ALLOWED_HOSTS in your Django's settings.py add the above copied domain names.
• Now deploy your Django app with eb deploy
• To deploy staged changes i.e. yet to be commit eb deploy --staged
• You can open the app with eb open
• To terminate the current eb env eb terminate

• The eb instance will automatically be setup with the ssh.
• You can connect to the ssh with eb ssh.
• In the ssh enter cd /var/log/ to navigate to log directory.
• In my experience with Beanstalk, there are three that are the most informative about deployment issues:

eb-engine.log
cfn-init.log
cfn-init-cmd.log

• To view last 100 lines from any file use tail -n 100 <LOG_FILE>.

• Setup aws ec2 instance with an Ubuntu machine.
• In Security Groups add Custom TCP with Port range: 8000 and 8080.
• Connect to aws instance via ssh.
• In Django's settings.py set ALLOWED_HOSTS = ['*'].
• Run Django with python3 manage.py runserver 0.0.0.0:8000.
• You server is running at port 8000, You can access it using your instance’s Public IPv4.

To Keep The server running

• Install screen with sudo apt-get install screen.
• Create a new screen with screen -S <screen_name>.
• Run the Django application inside screen same as you would have ran it in without screen.
• If you want to back to your main terminal press key shortcut ctrl+a+d.
• To continue with a screen screen -r <screen_name>.
• To remove a screen screen -X -S <screen_name> quit.

This way screen will keep the Django sever online even if you close the ssh client.
